At the homeless shelter, sitting on a folding chair in an out-of-the-way nook, he leaned in close to listen to a homeless man. He listened, then said a few words, then listened. I watched him from across the room. I would have asked him about the conversation, what was said? I never had the chance. Once the conversation ended, he made a beeline for the door. There could be no appearance of a broken confidentiality, no possibility that casual chatter might betray a trust. He just plain up and left and the men respected him for it.
